Check if a matrix is a Toeplitz or not .java

// Given an M × N matrix, check if it is a Toeplitz matrix or not. A Toeplitz matrix or diagonal-constant matrix is a matrix in which each descending diagonal from left to right is constant. // Any N ...

Directional Coherence Factor for Volumetric Ultrasound Imaging With Matrix Arrays

Abstract: Matrix arrays with small apertures limit spatial and contrast resolutions of volumetric ultrasound imaging. Coherence-based beamformers are prevalent for sidelobe suppression and resolution ...
